Movies you wish had a sequel

What are some films that were "one and done" that you wish ended up having a sequel or 2 to expand in their particular universes? I'm saddened that we never got a Mars Attacks or Coneheads follow up, they weren't the greatest comedies of all time but they were good in my book.

Gamera the Brave, IMPO was a good movie with some interesting ideas and i wanted more.

Chronicle was such a cool movie. Not a whole lot of people remember it, but it had a really good story to it, and plenty of mysteries still left to solve. It'd be cool to see another one that may help fill in so many of the blanks
